Filed: 1957-04-29
Abstract: The invention comprises compounds of the formula <FORM:0826837/IV (b)/1> wherein n is an integer from 2 to 4 and m is 2 or 3.  The compounds are made by halogenating a 2 - (o  - hydroxyalkylamino) - D 2 - 1 : 3 - diazacycloalkene to give the corresponding 2-(o -halogenoalkylamino) - D 2 - 1 : 3 - diazocycloalkene hydrohalide which is boiled with alcoholic potassium hydroxide to give the corresponding bicyclic guanidine.  The halogenation is suitably effected by treatment with thionyl chloride in chloroform.  In examples: (1) 2-(g -hydroxypropylamino)-2-imidazoline is treated with thionyl chloride and the resulting 2-g -chloropropylamino) - 2 - imidazoline hydrochloride (also characterized as the picrate) is treated with alcoholic potassium hydroxide to give D 8 - hexahydro - 1 : 4 : 8 - pyrimidazole (characterized as the picrate); by similar methods there are prepared (2) 2-(b -chloroethylamino)-D 2-tetrahydropyrimidine (hydrochloride and picrate) which on treatment with alcoholic potassium hydroxide gives the same product as in (1); (3) 2 - (g  - chloropropylamino) - D 2 - tetrahydropyrimidine (hydrochloride and picrate) and D 9-1 : 5 : 9 - triaza - bicyclo - (4 : 4 : 0) - decene (and picrate); and (4) 2-b -chloroethylamino- D 2-1 : 3-diazacycloheptene (hydrochloride and picrate) and D 9-1 : 4 : 9-triazabicyclo-(5 : 3 : 0)-decene.  Hydroxyalkylamino - diazo - cycloalkenes used as starting materials such as 2-(g -hydroxypropylamino - 2 - imidazoline, 2 - (b  - hydroxyethylamino) - D 2 - tetrahydropyrimidine, 2 - (g  - hydroxypropylamino) - D 2 - tetrahydropyrimidine and 2 - (b  - hydroxyethylamino) - D 2 - 1 : 3 - diazacycloheptene are made by treating the corresponding 2-methylthio-derivative with the appropriate amino-alkanol.  The compounds are isolated in the form of salts such as hydrochlorides, hydriodides or picrates, which are converted into the free bases by treatment with the hydroxyl form of an anion exchange resin.  1 : 3-Diazacyclohexanone is obtained as a by-product in Example 3. Specification 826,838 is referred to.

Abstract: 554,293. Furnaces for heating metal articles. WILSON, L. Sept. 28, 1942, No. 13616. Convention date, June 10, 1941. [Classes 51 (i) and 51 (ii)] The heat treatment of metal articles such as shells, wrist pins and the like of cylindrical or other form capable of rolling motion is effected by heating them while being traversed longitudinally between rotary tubular or like supports, the articles during their traverse being disposed parallel to the supports, the supports being heated internally by burners or by electric resistance elements to transmit heat to the articles. The articles are fed from a container 47 through shoots 45 into the grooves formed between closely spaced supports 24 rotatably mounted in a furnace chamber 14 with their ends passing through packing glands 27 in the end walls 13. The supports are rotated by gearing at one end and heated by burners supplied with gas from a pipe 36 and air from a blower and conduit 39 the gases being exhausted into a flue 43. Sealing rings 44 are arranged between the air conduit 39 and flue 43 and the ends of the supports. Conical portions 50 of the supports facilitate the discharge of the articles into the mouths of shoots 48 which deliver the articles into a quenching tank 49 where they fall on to and are removed by a conveyer 51. The furnace is mounted on supports so that it may be tilted by a jack 21 to cause the articles to transverse the supports by gravity. Where spherical articles such as balls are treated the furnace is tilted so that the supports are inclined upwardly towards the discharge end and the balls are moved by mechanical means along the supports. Such mechanical means may consist of a travelling feed chain or the provision of a spiral flight on one of the rotary supports. The supports 24 may be tapered or set at a slight angle to one another.
